Vfor use in cookiner stoves furnaces heaters and in tire pots of the large steam genen ating; boilers.

rllhe presentinvention is inthe nature of a modification of, or improvement on the hydrocarbon burner disclosed and claimed in my prior latent 1,199,177, oi date, September 26, 1916, and provides certain improved features which Very materially iniprove-the action of the burner by way of greater heating efficiency, ,more complete combustion of the hydrocarbon and resulting economy in the use of fuel. The means by and manner in which these improved re sults are accomplished, will be t'ully disclosed in the following description of thc commercial form ot' the improved burner.

In the drawings which illustrate' the burner, like characters indicate like lparts.

Vthroughout the several views.

lieiierring` to the drawings,

Figure 1 is a View chiefly in vertical sec tion but with some parts in full, showing the improved burner applied to a heater of the vwater or steam heatingsystem;

Fig. is an enlarged vertical section takenv on the line 2 2 of Fig. 1; and

"Fig: 3 is a horizontal section taken on the liner33 of Fig. 2.

The numeral 1 indicates the hot water heater, as an entirety, the same being of the usual or any approved construction.

1n the application ot' my improved burner, to the tire box or combustion chamber oi this boiler, the customary coal grate is removed and a large air intake tube 5 is tended through what is usually' the ash pit door opening and has an upturned end that terminates at the lower central portion ot' the combustion chamber lNot the heater.

ner end of the air intake tube 5 is a base plate (i which has a large central opening' i7 and surrounding air passages 8, which later ter, as shown, are `lrour in number. A. metal bowl 9, preferably a casting, formed independently oi the base plate (i, is seated in the opening 7 and has a flanged upper edge that rests upon the base plate 6 so as to thereby support the bowl while permitting independent expansion and contraction of the said bowl and base plate. rThis bowl 9 has an independent gas chamber 10 and has seiferal, as shown two, upwardly projected gas 4nozzles 11 that are preferably conical in forni and are provided with radiating perforations in their side walls. The lower ends oit these nozzles 11 are in open communication with the gas chamber 10. A. gas supply pipe l2 leads to the gras chamber 10, through the air tube 5, and from a point eX- terior ot' the heater and at its outer portion, is provided with a Valve 13, by means oi which it may be opened and closed, at will.

This burner is adapted to burn the heavier hydrocarbons and, in tact, will burn anything from crude oil to kerosene. it. liquid hydrocarbon is supplied to the burner from a suitable source, such as an elevated tank, not shown, through a so#called oil, supply pipe 14, which, at the exterior of il heater, has a valve 15. This oil pipe 1-'1 ia extended through the air intake tube 5, and its inner end is provided with branches 1/1 that are extended upward through the ,eras ,'hafmber 10 and lone axially through each olf the gas nozzles 11 to points above the same. PreieiIH ably, and as shown, the upper ends et the branch tubes 1K1A`l1` are threaded and screwed through the upper ends loi' the noffzles 11. To the threaded upper ends of thc branch tubes 14 are attached the upper branches or crowns of the so-called nozzle caps 1G. that are preferably bell-Shaped, or of conical4 form and surround the nozzles 11, but are spaced therefrom. so as toaiiiord ani'rulai.' passages between the two.

(iverlying the bowl il, and spaced vertcally therefrom is a hollow shell or so-called superheating' air chamber 17 that is closeilj at its` lop and has outwardly and dow wardly curved or extended tubular legs Il'', as shown, four in number. The lower ends or" theao tubular legs-z 1T rest upon the base plate t3 and register, one with each oit the air titi .tively insures this result the passages 8 thereof.' To loosely aline the lower ends of the legs 17'a with the said ports 8, the base plate G is provided on top with U-shaped alining ribs 6a which, yhile they keep the said legs in proper alinement, as stated, allow the same to expand and contract independently of the said base plate. r he air superheating chamber 17, in its bottom, is provided with air discharge ports l?" that aline with and immediately overlie,

ut are spaced from the crowns spective nozzle caps 16.

I have found that the best result-s and great efficiency can be obtained by the use of a small fan or blower arranged to 'work in the air intakeJtube 5. a fan or blower is indicated by the numeral 18.

he sameispreferably applied in the or receiving end of t-he said tube, and is secured to the armature shaft 19 of a small electric motor 20, .which latter, by means of suitable brackets, is secured to a d bearing ring 21 detachably applied to the said ktube 5, so that the motor and an and bearing ring may, as a self-contained structure, be applied to .or removed from the said air tube.

nace would the air tube predetermined draft. By speed electric motor, such the market, the force of will.

l/Vhere city gas,y for example, is available, propose to use the same, not only to start burner in to action, but to supply the nozzles 11 with al limited amount of gas using a variable as. can be had in the speed of the fan, and hence, the draft may be regulated at metallic parts hot, when the supply of.

hydrocarbon is cut off, and so that whenever the hydrocarbon is turned on, the generation of hydrocarbon gas and ignition thereof will be instantaneous.

Vhere this gas for maintaining the pilot light 'is notv available, the b to be primed in starting done by pouring a little lene into the bowl l9 and igniting the same, so as to heat up the nozzle caps and other metallic parts, as required to effect the initial generation of the hydrocarbon gas.

en the nozzle caps and other metallic parts of the burner are'once heated, the burning action will be as follows:

The hydrocarbon oil delivered from lthe pipe 14e and through the branch pipes 14 will How from the upper ends of the latter onto the crowns of the nozzle capslfi and will run down, or start to run down over the outer surfaces of the said caps. r1`he air supplied to,support the combustion being deand this may be kerosene or gasoof the reln the drawings, such urner will have live'red through the hot tubular and superheating cln.; .ber 17 livered as a downward blast directly onto the crowns of the nozzle caps lo. and will there meet the overflowinghydrocarbon so that the generation ol'I h rdroearlmn gas will be almost instantaneous and the resulting combustion which takes place will be entire and complete. The burning llames will he blown or dashed down into the bowl l), and being deflected, find a ready escape laterally and upward through the ample flame passages afforded between the tubular air intake legs 17. Thus the lianies are caused to come into contact with all of the metal parts of the burner and are dashed completely around the legs 17 and against the sides and over the top of the superheating chamair legs 1T will be deber 17, and from thence, complete the comi bustion within the combustion chamber 4"* and outlet passages of the heater.

lVhen the pilot burner is kept in action, the amount of city gas used may be reduced to a very small amount so that theV cost thereofl is very small. Of course. when desired, the city" gas or gas affording the gas supplied to the nozzles 11 may be cut off when once the burner is started into action. and the generating of hydrocarbon gas from the oil is properly started.

I very greatly improve the action resulting'from the manner in which the super heated air which supports the combustion is delivered in a downward direction, or against the crowns of the so-called nozzle caps, and hence, this arrangement, it will e understood, is highly in'lportant, regardess of whether or not the gas 'nozzles within the nozzle caps are or are not employed.

rllhe burner herein disclosed and claimed has not only been put into use and found eilicient, but has been commercially ut on the market, and in the use thereof, it is that in large, as well as in small heating plants or boilers, by the use of low grade ydrocarbons, greater heating effect to unit of cost is attained than can be attained by the use or coal in the ordinary commercial furnaces and boilers.

The term heater7 is used in a broad and liberal sense, and, obviously, will incl-nde the heat generating chambers stoves, furnaces, and boilers, wherein heat is' generated by combustion combustible fluid.
